Product Overview

The Woodward 9907-1290 is a ProAct Digital Speed Control unit designed to regulate engine speed by driving Woodward ProAct electromagnetic actuators. It processes magnetic pickup (MPU) signals and adjusts fuel rack position with high precision to maintain stable engine operation.
This module is supplied as 100% brand new original equipment, manufactured in the USA, and is widely used in power generation and mechanical drive applications for gas and diesel engines.

Technical Specifications

Engineering Advantages

• Precise Speed Regulation: Advanced PID control algorithms maintain stable engine speed under varying load conditions.

• Direct Actuator Drive: Eliminates external drivers by directly controlling ProAct actuators, simplifying system architecture.

• Software-Based Configuration: Adjustable via PC tools (e.g., Woodward ToolKit / Watch Window) for accurate tuning and calibration.

• Robust Design: Engineered for harsh environments with resistance to vibration and thermal stress.

• Comprehensive Protection: Includes fault detection for MPU signal loss, actuator issues, and power anomalies, with automatic failsafe shutdown.

FAQs

Does it support dual-fuel engines?
It depends on the application software loaded. The control logic must be configured to support multi-fuel operation.

Can it be mounted on the engine?
It is recommended to mount on a vibration-isolated panel rather than directly on the engine to protect internal electronics.

How is speed calibrated?
Calibration is performed via RS-232 connection using Woodward software tools, allowing precise tuning of speed and control parameters.

What is the product condition?
This unit is supplied as 100% brand new original equipment, with factory packaging and no prior operational use.
